HYDRAULIC TRANSPORTATIQN SYSTEIE.

Speccation of Letters Patent. Patented June, 13, 1922.

Application led August 19, 1921. Serial No. 493,648.

lhio, have ini-.vented certain new and usefulv improvements in HydraulicTransportation ystems. oil which the following' is a specification.

This invention relates to hydraulic sluieinp: and transporting systemstor ashes, mamitacturing refusa clay7 sand, gravel, rock, ore and othersolid substances, and its primary ohiect is to provide a simple,practical and h ifrhly eiiicient method ot givingauni Yform transportingcapacity to every part of a sluiccway or other conduit` irrespective ofdifferences in their grades,q cross-sectional dimensions or roughness.

l attain this object by continuously circulating through a part oit asluiceway or other conduit ot lesser transporting capacity than a.preceding or following part` a quantity of water which with the normaliow through the other parts is suilicient to carry the material. throughsaid part at a rate'equal to that ot the tull capacity of any otherpart.

My invention is particularly adapted for use in hydraulic transportationsystems wherein the transporting capacity of any part is limited bynatural topographical conditions, cost ot material. or othercircumstances. and it provides an economical method ot remedying acondition which ordinarily would necessitate a reduction in the y rateoi tee-d below the capacity oi the pump or other contrivance provided toconvey material to a point o' delivery.

Tn the accompanying drawings in the various views ot which like partsare similarly designated g Figure l represents a sectional elevation ota hydraulic. conveying system to which my invention is applied;

Figure 2. a similar elevation showing a diii'erent arrangementy ot theparts ot the system` and Figure 3 a plan view o'F a sluiceway showingstill another condition which would render the use oi my inventiondesirable.

Figure l oi the drawings shows a hydraulic sluicing or transporting svstem tor ashes. manutacturing refuse, clay. sand, ,Qraveh rock.y oreand other solid substances, including` a sluiceway 5. which is inclinedfrom an elevated point ot supply A to a sump or reservoir 6. from. wherethe material is conveyed to a point of delivery through theinstrumentality of a pump 7,

To illustrate the use and advantages ot my invention I have shown thesluiceway to he composed ot two parts one ot which, from C to D, haslesser hydraulic gradient or slope than the preceding part from to C,and a lesser transporting capacity than either the part A to C or thepart D to 0.

.lt is obvious that the transporting capacity oit the entire system islimited to that ot the part C-D, and to remedy this limitation, asupplementary quantity ot water is supplied at the upper end of sai dpart suliicient to compensate for the difference in its inclination withrelation to the preceding aart or its transporting capacity with rela1tion to the parts between which it is disposed.

The water supplied at the upper end of the part C-D ot the sluiceway isdrawn off at the opposite end of the same, after it has performed itsVfunction of increasing the transporting capacity of said part7 andunder conditions where a scarcity of water necessitates an economicalruse thereof, some or all et this water maybe returnedby means of a pump9 tothe upper end of the part C-D ot the sluiceway to repeatedly pertermits function in a continuous circulatory movement.

In the illustration shown in the drawings, the water is supplied to theupper end of the part C-D from a reservoir 8 through the medium oi thepump 9 and. a conduit l2 and is withdrawn at the lower end of the partthrough anv overliow l0 trom where it is conveyed to the pump 9 by apipe 13.

In Figure 2 ot the drawings I have shown the sluiceway as having apartE-F ot closed conduit following a part Fv-G of lesser transportingcapacity. The method of applying my invention is similar to that hereindescribed with relation to the construction shown in Figure l.

Figure 3 illustrates a sluiceway in which a part lll-K has a lessertransporting capacity than the preceding part K-Ti by reason oi adiiierence in their cross-sectional torni.

The application ot my invention to a sluiceway of' this character issimilar to the method illustrated in Figures l and 2 and needs nofurther illustration or explanation.

Having thus shown and described the apppcatjon of my improvements by thesimplest and most :feasible methods at present known to me, I desire itunderstood that variations in the arrangement of the parts may beresorted to Without departing trom the spirit of my invention.

It has been indicated hereinbetore that in places Where a plentifulsupply of Wateris available, the pump t'or returning of Water ttor reusethrough the retardingg` section oi the sluieeway mayv he eliminated, andit will he apparent that my improvements are applica-ble to closedconduits as Well as to open sluieeivays. and under conditions ditilerontfrom, those shown `in the drawings and hereinbeifore describedy which.necessitate an acceleration of the flow oit material through any partoit a hydraulic system for the conveyance of solid substances separat-efrom the other parts thereof.

Having thus described my invention, what I claim and desire to secure byLetters- Patent is:

l. In a hydraulic transportation system having in a sluiceway orConduit, a part ot lesser transporting capacity than another partthereof, means ttor continuously circulating a supplementary quantity ofWater through the part first mentioned for `the purpose of inrreasing'its transporting capacity, exclusive of said other part.

2. In a hydraulic transportation system l having in a sluiceivay orconduit, a part of lesser inclination than another part thereoh meansfor continuously circulating a supplementary quantity of'water throughthe part first-mentioned for the purpose of increasingr its transportingcapacity,y exclusive of said other part.

3, In a hydraulirv transportation system having in a sluieeway orconduit, a part oi lesser transporting` capacity than another partthereof7 means for supplying supplenientary Water at one end of the partfirst mentioned for the purpose of increasing its transporting Capacityand Withdrawing` 'this Water at the other end ot the same.

lll. In a hydraulic transportation system having in a sluiee-Way orConduit, a part oi lesser transporting capacity than an other v)artthereof, a source ot Water supply, a pump for Conveyinpr 'Water `fromsaid sourre to an end of the part first mentioned7 and an overflow Weirfor returning said Water to said source 'from the other end of thesaine.

5. The method ot equalizing the transporting capacity of a sluiceyvay orconduit having' apart otlesser transporting capacity than another part`Consisting in continuously circulating' a supplementary quantity ofWater through the part first mentioned, eX- elusive of said other part.

6. The method ot equalizing the transporting capacity ojl' a sluieewayor` conduit having a part ot lesser transporting capacity than anotherpart, consisting` oit supplying supplementary Water at an end of thepart first mentioned and withdrawing it at the opposite end of the same.V

-In testimony whereof I have a'liixed my signature.
